Allow the placeholder text for the date picker to be customized. For example, some may prefer "MM/DD/YYY" to be displayed instead of "month/day/year"

Thanks

When do you plan on releasing the Color Picker?

Any plans for a UI Query Builder that uses the Data Query component?

Make charts scrollable like how Google Charts implementing it:

add spinner component, so it can be used for waiting observable variable being resolved using Angular 4 new syntax

<ng-template #loading>Loading...</ng-template>
<div *ngIf="userObservable | async; else loading; let user">
  {{ user.name }}
</div>

Similar to the context menu in the jQuery suite - http://demos.telerik.com/kendo-ui/menu/context-menu
